Comment 3 for bug 154771

I have this problem too. On my first workstation I updated from Gutsy RC to Gutsy Final by installing all updates. After the release got out, update manager reported that a new version was available and launched the distribution upgrade tool, which stops at the second step, saying that my system is already up-to-date. Well, that's fine with me, but today I got it again, while there were no "normal" updates.
On my second workstation I installed Kubuntu Gutsy from the release cd from the 18th of oktober, and it has the exact same issue.

Safe to say that the RC was more stable than the final, as both the upgrade tool and kopete are broken in the final, while the weren't in the RC.
